Improved code to install dump1090 binary in net/dump1090 and hostname symlinks in net/hostname
Removed code that manually discards static archives in net/php
Miscellaneous SHA512 checksum updates and minor fixes in several net pkg build files
* Cause perl compile to fail prematurely if /usr/local/include directory exists. This directory
is unfortunately a preset fallback directory searched by gcc for some rust applications that
otherwise fail to compile for want of gcc toolchain-specific C++ headers that are otherwise
present in standard locations
* Fixed net/mutt homepage URL
